ARTICLES ..Harry Bradley,Leeds, England; assigner to John `Waddington Limited, Leeds,..Eng1and ,"ApplicationOctober 17, 1949, Serial No. 121,745 y"InGreatBritain November 6; 1948 This invention relates to cartons and like containers, and has for its chief object to provide a new or improved construction of carton which is collapsible for packing-or transport purposes when empty, and is4 capable'when erected of supporting as well as enclosingan article .placed therein.

A further object of the invention is to,.,pro.vide a carton or like container which is eminently suitable for wrapping or packaging articles such as electric lamps. A

A still furtherobject iswtoprovide a carton or container for electric lamps fwhich is virtually shockproof so that electric lamps can be stored or transported whilst in thevcarton or the like with little likelihood of damage.

According to the invention the carton or the like is constructed from a blank which when folded and erected affords a carton having inwardly projecting supports at one end upon which an article placed in the carton can rest. The supports will preferably be portions of a peripheral flap which is formed integrally with the body blank and is capable of being folded inwardly so as to lie against the inner faces of the carton sides, sections of the ap score or crease adjacent the ends of the body blank corner folds or creases being cut through, whilst the flap portions of the same length as said cuts are transversely scored or creased both centrally in line with the body blank corner folds or creases and at their ends whereby on erection of the carton these flap portions form the supports.

The peripheral flap may be provided with integral extensions or tongues which extend from the flap edge between the supports, `and lie centrally close to the inner faces of the carton side when it is erected.

Preferably at the other end of the carton will be provided a hinged or pivotal ap integral with each body side, these aps being adapted to ineline inwardly from the sides and end of the carton to encircle Ia portion of, and have a gripping or holding effect upon an article placed therein.

In order that the invention may be clearly understood and readily carried into effect, the same will now be more fully described with reference to and by the aid of the accompanying drawings, in which:

Figure 1 is a plan View of the fiat blank from which a four-sided carton is erected.

Figure 2 is a perspective View of a carton erected from the blank shown in Figure 1, with the contents.

Referring toFigure 1 `in Whichscoresior creases impressed or otherwise Vformed to facilitate folding of the blank are shown lbyV long and short dotted lines, the blank is" scored'- or creased' to form' four'cartonv sides, I,=-and -one of` the 1'free edges is formed with .a 'ap* 2jwhichI can be `Aglued or `otherwise secured to the fcorresponding'fedge 3 at the other side ofl theblank. 'One endof the carton blank is formed-with a'f'flapd, `creased at Eso that Ait can befolded-tolie closely-to Ythe sides I, and sections 6 of the crease adjacent the ends of the body corner creases 1 are cut through whilst the flap portions 8 ofthe same lengthas said cuts' `are transversely scored 'or creased both centrally at 9 in line with the body corner creases 'I, and at IIJ at their ends.

At the other end of the blank, each carton side I is provided with an integral flap, two flaps I2 being triangular in shape, and two flaps I3 being rectangular, the different shaped aps being alternate so that opposite sides of the carton have the same shape of flap.

Each flap I2 or I3 can hinge or pivot about its crease or score I4, and an arcuate recess I5 is formed in the free end of each flap.

The blank is folded over the centre crease or score 1, and the flap 2 secured to the corresponding edge 3 by gluing or the like, the overlapping end portions 8 of the flap 4 also being similarly secured. The carton is still in fiat condition and suitable for packing or transport purposes.

Referring also to Figures 2, 3 and 4, the carton is erected for use from this collapsed condition by manipulating it to form a rectangular tubular body, rand folding the flap 4 about its crease 5 into the interior of the carton so that the flap 4 and extensions II lie close to the inner faces of the sides I. The action of folding in the flap 4 causes the flap portions 3 to fold about their creases 9 and It) and assume the function of inwardly projecting supports (see Figures 2 and 3), at that end of the carton, and as shown in Figures 2 and 4, wherein said supports lie in vertical planes parallel to the longitudinal axis of the carton, an article such as the electric light bulb I illustrated will rest upon these inwardly projecting supports, and be retained in the carton although the end of the carton is vir- Y tually open. The electric lamp engages the extensions or tongues II which extend from the flaps 4 (see particularly Figure 4), the action of these tongues II being to prevent the supports 8 and flap 4 being pushed out from the interior of the carton by the careless or rough insertion of the bulb in the carton.

The flaps I2 and t3 may be folded inwardly about their creases to close partially the other end of the carton, either before or after the insertion of the electric lamp I6, and in the former event as soon as the glass portion of the lamp has passed the naps, they ride along to the cap of the lamp and grip the cap about its sides as illustrated most clearly in Figure 4. In either connection, it is preferable that the rectangular flaps i3 should be folded inwardly first, and the triangular flaps l2 arranged on the outside to ensure the maximum gripping and holding effect of the flaps upon the lamp cap, due to the overlapping oi the naps.

Whilst in the described embodiment, a foursided carton has been described, the invention is applicable to three-sided cartons, or even cartons having more than four sides, without departing from the features of construction characterising the invention.

1t will be seen that this invention provides a carton which is eminently suitable for electric lamps or valves, whereby they are completely protected, being at the same time adequately supported in the carton and visible through one or both ends, moreover the carton enables the cap end of the lamp to project sufficiently from the recess aorded by the turned in flaps to allow the lamp to be tested for light eioiency without the necessity of removing the lamp from the carton. I claim:

A carton for round-ended articles, such as electric light bulbs, having a four-sided body open at one end, a peripheral flap having hinged connections with only the central part of one end of each of at least two of the four sides and folded into the body of the carton at said open end, the flap being separated from the sides between the hinged connections adjacent to at least two of the corners of said body end by slits in line with the hinged connections of the flap to the said sides, the separated portions of the flap being folded inwards about scored lines parallel to the longitudinal axis of the body oi the carton to provide supports for the rounded end of the article, the peripheral flap also being provided with extensions in substantial longitudinal alignment with said hinged connections and extending beyond the separated portions or -the flap intorthe body of the carton parallel to its sides to engage the periphery of the rounded end of the article and thereby insure that the iiap remains in folded position.
